`This invention `relates to opthalmic mountings, and has particularreference to an im; prov-ed and more eiicient goggle structure. Animportant object yOf this'invention is to provide a goggle simple ofconstruction, light of Weight,and'inexpensive of manu- 't'actura Anotherimportant object pf this inveniiim is i9 provide a speel@ invheh lensesmay be easily and quickly inserted/.or removed. Y Still another lobjectof this invention is to providea goggle structure lhaving simple andeasily operated means lfor rigidly clamping the lenses in the eyepieces.`

Other ObisCtS find advent@ veiitoii, ipeiher with .the struction o' thesame, will readily become apparent ,duringthe course of the followinordescription. l -1 n ,the drawing forming a part of this specification,and in which have employed like numerals ,to designate correspondingparts throughout all views the same:

Figure 5 is a view similar to Figure 3, showing a modification of thisinvention.

In the use of goggles by Workmen engaged in Welding lor similarindustries, wherein they are subjected to a great degree oi' heat, theuse Q ,the ordinary type of goggle is impractical from a good manystandpoints. The only purpose ot va goggle A used in this Work is toshield the eyes of the wearer from the injuriousrays ot' the Weldingflame, such that any means for interposing between the light'and theWearers eyes a lens'ot light absorption glass meets the necessaryrequirements.V The usual goggle structures comprising as they do, heavyeye cups lWhich tit close to the face of the wearer, not only hinder the,Work ot the operator by obstructing vision to a great extent, but alsobecome' unbearably hot, and cause the eyes ot the operator to perspireand the lenses to subsequently become clouded with steam.l

It is the purpose o'f this invention to provide a goggle which is lightof Weight, sub- Siiiptieliv spaedfim the ffii-@.6 0f. ,the Opera# the"requirementsffor Work of this *character.k

Referring, ,them particularly t9 the diaviiie, wherein I have Sheva the'referred .epipvbodiment of this invention, t e numeralv 6 Same' isceniprpf the upperV Portieri 11 ali eiiieiidf: ing therethrough is Varivet 13 provided on Que end with the head li and Oli the @theirmember`16 of a snap fastenenp Ri idly clamped intermediate the 'head 11io? the rivet l,13, and-'the body portionof the'"bridge fore mentioned; yy

the preferred embodiment of thisV in- Veiiiipii the laver pprliieri 12pt.the bridge. 7 isfchannelefd at1`9 "to providea groove in 'whichissecured'by a `suitable rivet 120 the base portion21 of a resilient pad22 adaptn ed to form resilient rbearing means'l for the strap 17 toretain the same in taut position atafltirnes. i l

In Figure 4 of the drawing it may clearly beseen thatv the [eye pieces@are internally grooved, as at 23, toprovide retaining means for asuitable lens such as 24.

In Figure 5 of the drawing I have shown a slight modification of thisinvention, in which the pad 22 is eliminated, the strap 17 merelyencircling the tWo portions of the bridge. In the practical constructionof this goggle I prefer to form the same from some inexpensive and lightmaterial, such as iber, and to make the same of one piece. While I havefound fiber particularly applicable, any suitable material, provided itis slightly resilient, will serve if it is capable of being bent orsprung so as to separate the bridge at the split 10. In inserting lensessuch as 24, in a goggle of this structure,V the snap fastener isunfastened and the Strap allowed to hang free. WithV the strap in thisposition the two portions of the bridge may be sprung apart, whereby theeye pieces of the goggle are enlarged sufliciently to easily allow ofthe insertion of a lens. After the lenses have been inserted in the eyepieces, and the edges of the same t into the grooves 23, the frame isallowed to spring together again and is clamped in this position by.means of the strap 17 andthe head 18 of the snap fastener engaging withthe' base 16 thereof. In use it has been found that the resilient pad 22not only forms a comfortable nose pad, but also forms resilient meanswhereby the strap 17 is kept tight `at all times and various minordifferences in the sizes of the lenses to be inserted compensated for. vY t From the yforegoing description it may clearly be seen that I haveprovided a goggle structure in which the lenses may be easily insertedwith a minimum amount of trouble, and in which it is possible to conStantly insert or remove lenses without in any way decreasing Ytheefficiency of the frame. It will still further be seenthat a goggleconstructed in accordance with this invention will be very inexpensive,will be light and will be thoroughly adapted for the use of van operatorengaged in welding or similar processes. Y

While I have shown and described two preferred forms which I desire toconsider as the preferred embodiments of this inven` tion, it is to beunderstood that in the practical manufacture and use of the same it isexpected that various changes will suggest themselves, so that I reservethe 'right to make these changes as to structure, shape and arrangementof parts, in so far as I re main within the spirit of this invention andthe scope of the appended claims.

Having thus described my invention, I claim:

1. A goggle having two eyes and a split connecting bridge, a strapsecured to one half of' the bridge and adapted to be fastened about thesecond half of the bridge to clamp the two halves together, and aresilient cushion carried by the second half of the bridge andunderlying the strap where- 'ing a longitudinal split and a portion tofit the nose a resilient member on the nose litting portion, a strapsecured to one of the split` portions of the bridge and extendinfraround 'and over the'resilient member land interengaging `means on thestrap and the split portion of the bridge to which it is secured adaptedto hold the split portions closely together through the action oftheresilient member.

V3. In a device ofthe character described in combination with ,a lensframe having a pair of lens rims connected by a bridge having alongitudinal split and a portion to fit the nose, a resilient member onthe nose fit` ting portion, a strap extending from one split portionaround and over the resilient member, a male snap member extendingthrough one of the split portions and se* curing the strap thereto and afemale snap member on the strap adapted to engage the male snap memberand hold .the split members closely together through the action of theresilient member.

fl. In a device of the character described in combination with a lensframe having a pair of lens rims connected by a bridge vhaving alongitudinal split, a resilient member on one of the split portions, Vastrap connected to one of thel split portions extending over theresilient member and around the other split portion, and interengagingmembers onV the first split portion and the strap adapted to hold thetwo split portions closely together through the action of the resilientmember.
